Boscastle FloodWhy it happend

A disaster occurred in 2004 called the Boscastle Flood, it was a flash that only happens once in 400 years. stormy weather up to flood meant saturated ground where water flows underground and stops because their are rocks that cannot absorb the water, so the water flow travels sidewards and ends up in the river since there was a big flash flood where a whole month of rain came in the time span of 2 hours this kept repeating the process over and over again.

Another reason that ads on to the first would be a water slope this is when rain hits the hill and runs straight down into a river causing a flood that can take cars with it. example
